in the first movie, luke makes the choice that he's going to go follow ben kenobi to sort of pursue a lifetime in the force, to become a jedi. he makes that choice in the first third of the movie. >> you must learn the ways of the force, if you are to come with me to alderaan. >> alderaan? i'm not going to alderaan, i've got to get home, it's late, i'm in for it as it is! >> i need your help luke. >> the second movie, luke makes the big choice that he's going to abandon his training and go try to rescue his friends, exactly dead in the middle. >> luke. you must complete the training. >> i can't keep the vision out of my head, they're my friends i've got to help them. >> you must not go. >> but han and leia will die if i don't. >> the third movie, he makes the choice that he's not going to kill his father, the choice that the three movies have been leading up to. and he makes it at the end. and there's this beautiful progressive symmetry, first third, half, final third. and the movies work elegantly. and these are the kind of hidden structures that allow dramas like these to hang toget
